SM300608-1

Overview

The SM300608-1 is a general-purpose dynamic speaker manufactured by DB Unlimited. It features an 8 Ohms impedance and a nominal power rating of 300 mW. The device operates within a frequency range of 600 Hz to 20 kHz, with a self-resonant frequency of 600 Hz. It delivers a sound pressure level of 96 dBA when tested at 100mm distance. The physical dimensions are 30 mm in diameter and 5.1 mm in height, utilizing Mylar for the cone material.

Feature Summary

• Round shape design suitable for compact audio applications
• General-purpose dynamic technology for standard audio reproduction
• Mylar cone construction for durability

Applications

• Consumer electronics audio output
• Industrial control panel indicators
• General purpose alarm systems

Procurement Notes

Verify the specific datasheet version for the SM300608-1 to confirm exact mechanical tolerances and electrical characteristics before integration. Ensure compatibility with driving circuits capable of handling 8 Ohms impedance. Check for RoHS compliance documentation if required for your region. Confirm mounting style requirements against the flange mount specifications provided in official DB Unlimited documentation.

Selection Notes

Select this component when a round, low-profile speaker is required for general audio tasks. The 300 mW rating suits low-power applications. Consider the 600 Hz lower frequency limit; it may not be suitable for full-range bass-heavy music. Verify that the 96 dBA efficiency meets the volume requirements of the enclosure design.

Part Context

This part belongs to the SM series of dynamic speakers from DB Unlimited. The series offers various sizes and shapes. The SM300608-1 specifically provides a balance between size and acoustic output for small enclosures. It is distinct from rectangular or higher-power variants in the same product line.

Replacement Considerations

Direct substitutes must match the 8 Ohms impedance, 300 mW power, and 30 mm diameter. Check for identical mounting hole patterns and depth constraints. Verify frequency response curves if specific tonal quality is critical.
